Do Motorcycles Have TPMS? What Is Actually Fitted Most motorcycles leave the factory without tyre-pressure monitoring. Why two-wheelers were left out of the car mandate, and where retrofits actually live.

The short answer

Most motorcycles do not have TPMS. A small number of premium touring and adventure models offer tyre-pressure monitoring as a factory option, and a handful of high-end machines include it as standard, but across the two-wheeler market as a whole it is the exception rather than the rule. For the vast majority of bikes on the road, if there is pressure monitoring at all, it was fitted after the bike was bought.

That gap is the reason a retrofit market exists at all — and it is a more interesting story than "motorcycles are cheap", because it is not only about cost.

What is actually fitted at the factory

When a motorcycle does come with pressure monitoring from the factory, it usually appears in one of two places.

On premium touring and adventure models, where the buyer has already paid for heated grips, cruise control and a colour dash, a pressure readout is a natural addition and the wiring and display already exist.

On some scooters and light commuter models in markets where the importer has asked for it as a differentiator.

What almost never happens is a pressure sensor on a small commuter bike, a moped, a delivery scooter or a budget motorcycle. Those are the highest-volume two-wheelers in the world, and they are the ones with no monitoring at all.

Why two-wheelers were left out

Four reasons, in roughly the order they matter.

No legal requirement. Several major markets require TPMS on new passenger cars, and have done for years. Two-wheelers were not brought into that scope. Without a mandate, a factory has no reason to add a component that costs money on every unit and adds a warranty exposure.

The rider notices a soft tyre sooner. A motorcycle is a single-track vehicle: a tyre that has lost pressure changes the steering and the way the bike falls into a corner within a few kilometres. On four wheels, a slow puncture can go unnoticed for weeks. That genuinely reduces the perceived need — though it does nothing for the failure that matters, which is a fast loss of pressure at speed.

Display space and wiring. Adding a readout means finding somewhere for it on a machine with a small instrument cluster, and routing a harness on a vehicle built to a tight weight and cost target.

Service friction. Two-wheeler tyres are replaced far more often than car tyres, in more places, often by small workshops. Anything that makes a tyre change more complicated — an internal sensor on the rim, or a valve that has to be handled carefully — meets resistance at the point of service.

The regulation picture, in plain terms

There are UN regulations and national rules that apply pressure monitoring to certain vehicle categories, and the details differ by market and by vehicle class. The practical summary for a two-wheeler buyer or distributor is this: for the motorcycle categories, monitoring is not something you can assume is required, and it is not something you can assume a factory has fitted. If you are importing or building to a specific destination, the applicable rules for that market and that vehicle category are a question to be answered in writing, per project, not taken from a blog post. That is how we handle it for our own customers.

What riders do instead

In the absence of factory fitment, three things happen.

Nothing. The most common outcome. The rider checks pressure occasionally with a gauge, usually before a long trip, and lives with the uncertainty in between.

A retrofit system with its own display. A sensor on each valve and a small screen on the handlebar. It works, it is self-contained, and it does not depend on a phone — but it is another thing to mount, power and look at.

A Bluetooth system, with the phone as the display. The sensor broadcasts, the rider runs an app, and there is nothing to wire into the bike. This is the arrangement that has grown fastest in the two-wheeler aftermarket, because it removes the two things that stopped people fitting a system: the harness and the display. The motorcycle applications page shows how the wheel counts map onto typical bikes, scooters and three-wheelers.

What a retrofit has to get right

A retrofit system is fitted by whoever owns the bike, or by a small workshop, so the design has to survive that context.

It must not require a tyre change. Valve-stem replacement sensors are fitted without removing the wheel, which is what makes them realistic for the aftermarket.

It must be sealed against weather. The sensor sits on the valve in rain and road spray. Water-immersion testing is a minimum, not a luxury.

It must not demand a re-pair after a battery change. Every extra step in the owner's life is a reason the app gets deleted.

It must be marked by position. Front and rear sensors that look identical and are not marked will eventually be fitted the wrong way round.

It must be honest about a missing reading. If the phone is out of range, or the sensor has not transmitted, the app must say so rather than keep showing the last number.

On our sensors the operating range is −20 °C to +80 °C, storage −40 °C to +85 °C, humidity 5–95% non-condensing, and the CR1632 cell is user-replaceable without re-pairing. The full specification is on the BPU100 product page, and the app side is covered on the app page.

Where we stand

We build BLE TPMS sensors for two-, three- and four-wheel vehicles, and the two-wheeler aftermarket is where most of our volume sits: more than 10,000 sets a month in China, with capacity of 30,000 sensor units a month from our own line in Shenzhen. Eight in-house test steps run before shipping, including pressure calibration on every unit, water immersion, RF range, protocol verification, powered ageing, battery current, appearance and dimensions, and a full wheel-position system test. Certification is handled per market and per project, and we will confirm the current status in writing rather than leave you to assume it.

If you are looking at the retrofit opportunity for a specific market, tell us the vehicle categories and the destination and we will set out which configuration fits and what would have to change.
